Well, there was "Mr. Green" there, so at least one man was without fancy title, and the erstwhile deceased, "Mr. Body", but the other man is "Colonel Mustard", and the women are Miss Scarlet, Mrs. White and Mrs. Peacock, IIRC. So it appears that you have a point there. Gender bias in classic board game! We'll have to get Parker Brothers on a recall campaign...

Of course "Miss Scarlet" always gets to go first, though, and for all his education, the stately Professor Plum always goes last.
